Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a modular distribution box. Background Technology

[0002] Currently, all distribution box products on the market have an integrated structure, complex mold structure, and errors in thread concentricity, which can easily lead to insufficient fit between bolts and threads during assembly. During assembly, the bolts and threads of the upper and lower covers do not fit together.

[0003] In summary, this utility model designs a combined distribution box with good sealing effect and high bolt thread fit. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combined distribution box with reasonable structural design, good sealing effect, and better protection against rainwater penetration, making it highly practical.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a combined distribution box, including a box body, wherein the four corners of the box body are provided with pre-embedded threaded holes, the pre-embedded threaded holes cooperate with threaded inserts, the box bodies are connected by sealing gaskets, clips, plug rods and wedges, the clips are snapped into the grooves of the overlapping parts at the upper end of the distribution box, and the plug rods pass through the plug holes at both ends of the adjacent distribution boxes and are fixed by wedges.

[0006] Preferably, the threaded insert is made of bolt or spring clamp.

[0007] Preferably, the threaded insert is externally coated with rubber.

[0008] Preferably, the boxes can be spliced ​​together indefinitely.

[0009] Preferably, the bottom of the box is provided with a sealing groove, the box cover is provided with a pressing protrusion, and the bottom of the box and the box cover are sealed and fixed by polyurethane foam or silicone strips through the bottom sealing groove.

[0010] Preferably, a padlock hole is provided between the box cover and the threaded insert, and the padlock is locked by fastening bolts and the box cover lock hole.

[0011] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonable. It adopts the structure of pre-embedded threaded inserts. The bolts and threads are of the same size, which has a good fit and can be replaced at will. The thread and bolt sizes are the same, which will not cause the bolts and threads to mismatch during assembly. It is easier to seal and can better ensure that rainwater will not seep in.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Reference Figure 1-4 The specific implementation adopts the following technical solution: a combined distribution box, including a box body 1, wherein the four corners of the box body 1 are provided with pre-embedded threaded holes 2, the pre-embedded threaded holes 2 cooperate with threaded inserts 3, the box bodies 1 are connected by sealing gaskets 4, clips 5, plug rods 6 and wedges 7, the clips 5 are snapped into the grooves 8 of the overlapping part at the upper end of the distribution box, and the plug rods 6 pass through the plug holes at both ends of the adjacent distribution boxes and are fixed by the wedges 7.

[0019] It is worth noting that the threaded insert 3 is made of bolts or spring clamps.

[0020] It is worth noting that the threaded insert 3 is externally coated with rubber.

[0021] Furthermore, the assembly of the aforementioned box 1 is based on an infinite number of 150*300mm units.

[0022] In this specific embodiment, the threaded holes at the four corners of the distribution box are pre-made parts that are embedded during injection molding and then coated with rubber for a more aesthetically pleasing appearance. Internally, they are connected to the top cover via threaded inserts, which can take various forms, such as bolts or spring clamps. The distribution box uses a base size of 150*300mm and can be freely combined and infinitely spliced. Available sizes include: 300*150*180, 300*300*180, 300*450*180, 300*600*180, 450*600*180, and 600*600*180 (unit: mm). The box is joined by aligning side walls of the same size and using pre-drilled wedge holes in the side walls for tenon and mortise joints. Waterproofing is achieved by clamping a sealing strip between the two spliced ​​surfaces. The overall protection level after splicing is IP66 / 67. The enclosure features a sealing groove at the bottom and a pressing boss on the cover. A seal between the bottom and cover is achieved using polyurethane foam or silicone strips in the sealing groove. The overall protection rating is IP66 / 67. A padlock hole is provided between the cover and the bolts; tightening the bolts and the cover lock hole secures the padlock, preventing unauthorized opening. Pre-drilled joint holes on the side walls allow for the installation of flanges to accommodate different side-wall cable entry / exit conditions. The threaded bottom of the enclosure is achieved through pre-embedded threaded inserts and injection molding.

[0023] In this specific embodiment, the bolts and threads are of uniform size and are embedded inserts. This ensures that the bolt and thread dimensions are consistent, preventing mismatches during assembly, making sealing easier, and better ensuring that rainwater cannot penetrate.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
